科學圖說

位於地底深處的岩層,漸漸地暴露到地表時,由於壓力減小,岩石產生了裂痕,因此岩石和空氣與水的接觸面積增加,會沿著岩石的節理進行風化作用。若水中或岩石內含有鐵的成分,在長期風化作用下,鐵質會氧化生成氧化鐵,顏色也轉為褐色或咖啡色。氧化作用越完全,風化紋的顏色也越深。加上受海水長期淘洗而剝落,地層擠壓出縱橫交錯的裂縫,便生成彷彿鬼斧神工般的奇岩異石。

Introduction

When rock strata that were once deep underground are gradually exposed, the pressure decreases creating fissures. This increases the contact area of the rocks with air and water along the joint, leading to erosion. If the water or rocks contain iron, over a long period of weathering the iron oxidizes to become ferric oxide. This leads to a change in color to brown. The more complete the oxidation, the deeper are the colors of the patterns. Due to the long term effects of sea water, a network of fissures has formed along the surface creating an intricate work of natural craftsmanship.
